Abstract: PURPOSE:To contrive complete deaeration inside a container before starting extrusion by providing a vacuum assisting valve integrally with a hydraulic switching valve in the middle of piping between a container and a vacuum pump and abutting the container on a die through the detection of a vacuum state. CONSTITUTION:An end face of a container 1 is stopped with a clearance 6 between the end face and a die ring 5, a billet 13 is inserted with an extruding stem 14 with a tip end abutted on a die 3. Simultaneously, an exit of a vent is opened by an air actuator 25. In addition, when the extruding stem 14 is advanced to start upsetting, and a billet 13 on the side of the extruding stem 14 enters into close contact to the container 1, the air in a deaerating space 31 is sucked from a die 3 side. When the inside of the container 1 is filled with the billet 13 with the degree of the vacuum approaching 0Torr, a spring 45 is pressed downward by the piston 44 of a vacuum assisting valve 42. When the piston 44 is lowered to a protrusion part 43a, a hydraulic switching valve 47 is switched, and the container 1 is pulled to the die 3 side by a cylinder 33, closing the clearance 6 and stopping the suction of the remaining air. Then, successively, extruding is commenced.

Title: Pressure oil flow rate controlling equipment for automatic gear
Inventor: NISHIKAWA MASAO
IPC: F16H61/10
Filed: 1985-03-28
Abstract: PURPOSE:To enforce two-stage control of the flow rate of pressure oil through a single valve by installing the valve, designed to execute an opening and closing control in accordance with the state of engine output, in a by-pass oil route formed in parallel with an oil supply route from oil pressure source to a changeover equipment and installing an oil flow rate reducing part in the oil supply route in parallel with the by-pass oil route. CONSTITUTION:In parallel with an oil supply route 38 from an oil pressure source to a changeover equipment, a by-pass oil route 66 is formed with a control valve 74, designed to enforce make-and-break control of the oil passage 66 in line with the state of engine output, installed in it. On the other hand, a flow rate reducing part 65 is installed in the oil supply route 38 running in parallel with the by-pass oil route. When the by-pass oil route 66 is shut by the control valve 74, flow volume of pressure oil to the changeover equipment is restricted by the oil flow reducing part 65. When the by-pass route is open, pressure oil is provided to the changeover equipment without any restriction. In this way, the two-stage, variable control is effected by means of a single valve.

IPC: H02G1/02
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a method and device having a simple constitution with which the confirmation of the connection of by-pass cables can be executed surely. SOLUTION: A power line is composed of a main feeder and branch feeders and a by-pass cable 11 is connected to one of the branch cables, which are branched correspondingly to the main and branch feeders by connecting a switch 3 for construction to the branch cable. Then, after the by-pass cable 12 of another branch cable is connected to a power main feeder 100 of the power line, a by-pass cable 14 of one branch cable is connected to one branch feeder 101 of the power line, so as to detect the shunted current flowing to the by-pass cable of the charging current flowing to the shield layer of the by-pass cable and the conducting current flowing through the power line. Consequently, the branch feeder and one branch cable can be connected to each other at the same potential state.  Therefore, the connected state of the by-pass cables can be confirmed by preventing the occurrence of imperfect connection, which turns into an intermittent discharging state between the branch feeder 101 and one branch cable.
